Designed for movement, built for the mountains, and refined for versatility, the Rime Light IN Hybrid Vest delivers dependable warmth without excess weight. This lightweight hybrid insulation piece blends wind-resistant outer fabric with breathable stretch fleece zones, creating a vest that regulates temperature efficiently while maintaining unrestricted mobility.

At the core is Mammut LOOPINSULATION®, a low-profile, recycled synthetic insulation that provides consistent warmth where you need it most, without trapping excess heat during high-output efforts. Whether worn as a standalone layer on cool ascents or as a midlayer under a shell, the Rime Light IN Hybrid Vest adapts effortlessly to changing conditions.

Wind- and abrasion-resistant with a soft hand feel, it packs down small and stows neatly into its own pocket, making it an easy addition to any pack. With an athletic fit designed for clean layering and backpack-compatible pockets, this vest is a reliable companion for long days across varied terrain.
